Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] like Figures 1 to 4 As shown, a whip antenna storage and release mechanism according to the present invention includes a base 10 on which a whip antenna 20 is fixedly arranged, and the whip antenna storage and release mechanism further includes storing the whip antenna 20 into a disc shape. And fasten the hot-melt rope 30 on the base 10 , and the base 10 is also provided with a heating device in contact with the hot-melt rope 30 . In the present invention, the whip antenna 20 is fixed on the unit through the fixing device 21 to complete fixing and signal transmission. When the whip antenna 20 is stored, the whip antenna 20 is rolled into a disc shape, and then the coiled whip antenna 20 is tied to the base 10 by using the hot melt rope 30, which effectively saves the storage space; 10 is provided with a heating device t...

Abstract

The invention provides a gathering and releasing device of a whip antenna. The gathering and releasing device comprises a base, the whip antenna is fixedly arranged on the base, and the gathering and releasing device of the whip antenna further comprises a hot melting rope which enables the whip antenna to be gathered into a disc and fastened on the base, and a heating device contacted with the hot melting rope is further arranged on the base. By means of the gathering and releasing device of the whip antenna, the whip antenna is banded by the hot melting rope to be in a shape of a disc, a gathering space is effectively saved, when the whip antenna is released after entering a track through the heating device fitted with the hot melting rope and arranged on the base, the heating device is opened, accordingly the hot melting rope is broke, binding on the whip antenna is released, and the whip antenna is reliably expanded under self elasticity of the whip antenna. Gathering and releasing of the whip antenna can be achieved through matching of the hot melting rope and the heating device, and the gathering and releasing device is simple in structure and high in reliability.

Description

technical field [0001] The invention relates to the field of satellite antenna storage mechanisms, in particular to a whip antenna storage and release mechanism. Background technique [0002] Micro / nano-satellites usually use VHF / UHF frequency band measurement and control or carry electronic reconnaissance receivers in this frequency band, and the radio wave wavelength of this frequency band is meter level. Because the size of the antenna is comparable to the wavelength, the length of the antenna in this band is long, usually larger than the size of the satellite body. Micro / nano-satellites are usually launched in a mounted way, and the space provided by the rocket is limited, so the VHF / UHF antenna of the micro / nano-satellite is usually required to be a flexible antenna, which shrinks in the active section of the rocket to reduce the space occupied by the rocket. After entering the orbit, control the storage mechanism to release the antenna by sending a remote control comm...
